Abstract

Humanoid robot itself is a robot that has human-like characteristics. Starting from the physical structure in general humanoid robots have a head, two hands, two legs, but there are some humanoid robots that are very humanoid such as having a waist to the upper body or even a face. . The purpose of this study is to allow the robot to move steadily and balancedly according to the willingness of the tester. This humanoid robot can perform walking, running, jumping, dancing, and much more. Simple gestures such as walking require alignment between actuators, controllers, and built-in programs or commands. It uses an OpenCM 9.04 controller and Gyroscope sensor as its balancing sensor.  Gyroscope sensor used by MPU-6050 which has an output in the form of angular velocity from the direction of 3 axes that is, the x axis that will later become the angle of phi (right and left), and the y-axis will later become theta angle (top and bottom), and the z axis will later become psi angle (front and back). Gyroscope sensors will be implemented to the legs of humanoid robots so that humanoid robots will maintain their balance in standing and walking later. The robot used is a Bioloid Type-A humanoid robot. The results of this test the robot can move as expected by the author and add value to the test results of the programming process of the OpenCM 9.04 microcontroller. Keywords: OpenCM 9.04, Gyroscope, MPU-6050, Bioloid Type-A humanoid robot.

Abstract

With the development of technology, the speed of access to information is increasingly needed. The network is not only connected but also must be stable, fast, and smooth. Therefore, it is necessary to build a system that divides the bandwidth for each employee of an organization/office using a router. In this study, a bandwidth management system will be created that divides the bandwidth of 30 Mbps for employees at Bank BTN. This can be done by ensuring that every user who accesses the internet will get the same bandwidth allocation on the network. The system's design aims to make downstream speeds by limiting the internet access used at the BTN bank office for each employee. Based on the research that has been done, the best throughput results for employees in the morning on the third day are 91% with an index of 4 and a very good category. While the worst throughput results for employees in the morning on the first day were 81%, with an index of 4 and a very good category. Moreover, the overall throughput results obtained an average of 84% with an index of 4 and a very good category.Keyword: Bandwidth, Quality of service, Througput.

Abstract

SMAN 5 Bangko Pusako is one of the senior high school that has implemented 2013 Curriculum in its assessment standards. However, due to evaluation standard of 2013 curriculum is more complicated so it makes teachers feel difficulty in marking process. In addition, the marking process in SMA N 5 Bangko Pusako still uses Microsoft Excel where every subject teacher has their own grades file, then the homeroom teacher will unite all the grades of the subject teacher and reprocess it to be used as a report card. The lack of integration of marking process between subject teacher and homeroom teacher makes the marking process takes a long time, so we need a web-based marking process information system that can facilitate the work of teachers in marking process in 2013 curriculum is needed. This information system is created by using PHP Programming Language and MySQL as database. The results of this study are information systems that manage web-based values that apply 2013 curriculum assessment standards so teachers do not feel difficulty in calculating grades. In addition, this information system can integrate and calculate all grades from the subject teacher and homeroom teacher, then the final grades can be printed directly into report cards. In this system, Naive Bayes Method is also used for prediction of students’ field. Function to predict are made by using RapidMiner, which is provide an accuracy of 95,24% with an error rate of 4,76%. Keywords : Information System, 2013 Curriculum, Marking Process, PHP, MySQL

Abstract

At the time of installation the distance between the shear reinforcement is not planned properly. This affects the serviceability of reinforced concrete blocks. This study aims to see the effect of the planned shear reinforcement which is not according to the initial plan. So, an analysis of the effect of shear reinforcement on deflection was carried out using the LUSAS Finite Element. The results of the LUSAS Finite Element analysis show that the BS2 beam model with a maximum load of 40.5 kN has decreased deflection by 33.53 % against the planning according to SNI 03-2847-2019 (BS1) which has a maximum load of 46.55 kN. Furthermore, for the BS3 model with a maximum load of 38.69 kN, the deflection decreased by 35,03 % from the planning according to SNI 03-2847-2019 (BS1) which had a maximum load of 46.55 kN. It can be concluded that the spacing of the shear reinforcement can affect the deflection of the beam. Keywords : Beam, Shear Reinforcement, Deflection, LUSAS
